Let me see if I can answer these for you:

03GTPLE, after reading the entire HID thread you linked to, it seems like everyone is getting super confused between the 97-03 and the 03+s. i have an 02 and a will be getting some DDM's soon.

Which ballast's did you get? I got the DDM HID Kit Slim Ballast (35W), it's the black ones (if you're looking at the silver or black ones). They can be found here: HID Kits, BMW Aftermarket Bumpers & Lighting, DEPO - DDM Tuning

and you were saying the hi/low function doesn't work very well at all? They say a 9007 bulb uses axial filaments meaning the high and low filaments are above and below one another, which sounds like the telescoping HID bulb that DDM sells should work perfectly, right? anyway, let me know.

The bulb does telescope to change between high and low. However, not enough; at least for the stock headlights. I don't know what's going on here, but when I switch between the high and low beam, I can notice a change, but the beam pattern gets worse. Thankfully, the lights are brighter than high beams and I haven't had a need for brighter light. I've driven on very dark roads at night, and at highway speeds and that would be the time you need that, but the "low" is bright enough to keep me covered.

...yes, DDM said it was supposed to work... I just didn't want to mail bulbs and whatnot back and forth. Customer Service is good.

Also, did u get HID fogs too? and also from DDM? Nope, stock. My stock fog lights don't provide any extra light. They used to be brighter than the headlights, even brighter than the sylvania silverstar ultras... but now my HIDs over power them

You also got the harness, would you recommend it? I would recommend the harness. The big reason why I got the hi/lo combination was because that package comes with the harness, so the cost is the same.

Looks like they changed the website around a little bit; and they are out of stock on ballasts until the 20th, which is tomorrow. I had to wait three weeks before mine got in..........

As far as the error eliminator kit, that's up to you. With my kit, it leaves the passenger side OEM bulb unplugged because ther DDM harness only connects to one bulb connection. For some reason, my brights indicator on my dash and HUD is constantly on. It's dimmer when the brights are not actually on, but it's still there. It does not bother me, and I don't know if the error eliminator will fix it. I was planning on plugging in a stock bulb to see what would happen, but I just haven't tried it yet. ....so... that's up to you, and I really have no idea if the error eliminator kit will fix it.

...and you don't need the adaptor cable, just to cover the bases.






That being said, again, I'm very happy with them, and will move the kit from car to car

Let me know if you have any other questions.
